Amdro Mole and Gopher Bait is labeled to kill moles and gophers. If you follow the labeled instructions to treat for either of those, then it should be effective in Arkansas.
The product label states, "Do not apply in gardens and areas where food or feed may become contaminated." We would recommend contacting the manufacturer directly for further information on this, as the product label does not mention a certain wait time to replant.
